Hi all, We plan to buy solder paste height measurement machine. However, not sure which is the better one..2D or 3D? As far as I know,3D is quite slow and but more accurate in term of measurement result. Pls share with me if anyone who has this e

�It adds NO VALUE whatsoever to do 3D inspection as part of in-line production.�

Hi, yes may be 3d is slow but it gives you great results as it shows the height while 2d picture shows error when the paste in your machine appears to end i.e. when it see that the pad starts to appear. I don't know which company brand you prefer but

Good Morning, We have a 3D solder paste inspection machine. We purchased it on a recommendation from a consultant. We are a CM high mix low volume. The President of my company has attended some seminars and meetings where it was conveyed to her that

Seminars and meetings are the best way to get a clear understanding of a machine's capabilities. I have found that the manufacturing engineers will oftentimes skew the results of machine evaluations with facts and data. In practice, I've found it

Question...when the machine said something was wrong, was it reading something wrong (false failure), or was there a true descrepancy but not one that resulted in a bad connection (bridge or insufficient)? Also, did you perform a DOE on the process

In short this guys are not well updated on the new technology of SPI. True, 3D IN LINE SPI is no longer a slow machine. Try checking some brand like Cyberoptics,Synapse imaging,SEIMENS,KOHYOUNG and many others...they can match the speed os some mount

Hi Dub J, I have worked for a few companies that did 3D sampling and found the data they produce to be useless. In the real world they are slow, so that means you won't sample every board. Now if you're not sampling every board, and you start to r

3d is good for initial verification that your screen printer and stencil is producing the desired paste height. 2D verification is more than sufficient during regular production. That being said, your best bet for a 3D machine is to go cheap - buy

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu
